Cable holder

ABSTRACT

A cable holder for a cable includes a guide section for guiding the cable that can be pivoted in sections for a change in direction of a run of the cable.

BACKGROUND OF THE INVENTION

Domestic appliances have a large number of electrical components whichare supplied with current via power supply cables or controlled by meansof control leads. For this purpose it may be necessary to run cables viaone or more housing edges of the electrical component.

In order to simplify power supply cable installation, it is known to usecable holders having at least two guide sections which are angled to oneanother and matched to the external contour of the electrical component.The cable holder can be fitted with the relevant cables separately fromthe appliance and then installed in the appliance. By means of themutually angled guide sections of the cable holder, cables can be easilyrun round edges of the electrical component's housing.

The cable holder with its two guide sections is usually a pre-profiled,rigid component which is installed with its angled guide sectionsabutting the electrical component.

Fitting such a cable holder with power supply cables remains a complexassembly operation because of the mutually angled guide sections. Inaddition, this kind of pre-profiled cable holder is altogether bulky andtherefore can only be stored and packaged in a space-intensive manner.

BRIEF SUMMARY OF EXEMPLARY EMBODIMENTS OF THE INVENTION

An object of the invention is to provide a cable holder which simplifiescable installation, particularly in a domestic appliance.

The invention proceeds from a cable holder for a cable, in particularfor electrical conductors or fiber-optic cables, having one or moreguide sections for guiding the cable.

One or more guide sections of the cable holder are not rigid, butpivotally disposed on the cable holder. To enable the power supplycables to be fitted particularly simply during assembly, the one orpreferably two guide sections of the cable holder can therefore bedisposed aligned to one another in a common assembly plane in which thetwo guide sections enclose an angle of 180°. During fitting, the cablescan therefore be guided round edges without complex assembly. Moreover,the cable holders can be compactly packaged to save storage space. Inthe packaging position, the two guide sections can lie side by side, forexample, i.e. with an angle of zero between the two guide sections. Thetwo guide sections of the cable holder can be placed in their mutuallyangled installation position only for final assembly.

To facilitate handling of the cable holder, its two guide sections areconnected together via an articulated joint such as a hinge region, inparticular a living (integral) hinge. In this case, the guide sectionscan be folded out into an installation position or a cable fittingposition, depending on the assembly operation, or alternatively foldedtogether in a packaging position.

In their installation position, the two guide sections of the cableholder can preferably be positioned so that they directly match theoutline at the electrical component of the household appliance, it beingadvantageous in terms of assembly for the guide sections and theelectrical component to be snap-fit together without the use of tools.

The two mutually adjustable guide sections of the cable holder canpreferably be folded completely together in their packaging position sothat the two guide sections lie side by side in the longitudinaldirection. In this case, at least one of the above mentioned snap-lockelements can serve the dual function of providing a snap-lock connectionwith the electrical component and also securing the adjacent guidesection and engaging it accordingly in a snap-locked manner.

In a particular embodiment, the cable holder can be adapted for use in adomestic appliance, in particular a water carrying domestic appliancesuch as a dishwasher or washing machine. A dishwasher usually has, onthe inner metal plate of its door, a housing of a dispenser whichconstitutes an electrical component within the meaning of the invention.The dispenser is known to be provided with electrical actuatingelements, such as a magnetic coil and an electrical low rinse aidindicator. The cable holder can be mounted in the installation positionon the housing of the dispenser via the abovementioned snap-lockelements.

The door of the dishwasher can be implemented with, facing thedishwasher cavity, an inner metal plate on the outer side of which adoor exterior, e.g. an enclosed fascia or a decor panel. For factoryassembly of the appliance door, the frontally still open, trough-shapedinner metal plate is hinged to the dishwasher via lateral hinge levers.In order to facilitate hinging actuation of the inner metal plate hingedto the dishwasher at this stage of assembly, one of the guide sectionsof the cable holder can be implemented with a handle. The handle can bea gripping bar raised up from the guide section.

For safe actuation of the handle formed on the guide section, thesnap-fits of the cable holder to the housing of the dispenser must beimplemented in a sufficiently stable manner. It is therefore preferableif, in addition to the snap-fits on the dispenser housing, at least oneguide section of the cable holder is additionally also coupled directlyto the inner plate of the appliance door. Pulling forces exerted on thecable holder when the handle is actuated can therefore be reliablyabsorbed by the inner plate of the door.

It is preferable in production engineering terms if the guide sectionsare of the same material and/or of a piece with the hinging region andthe snap-lock elements. In this case, the cable holder can be simplymanufactured as an injection-molded part. Particularly with an angle of180° between the two guide sections, the cable holder can beadvantageously produced using simple forming dies without additionalslider components.

The invention also relates to a domestic appliance having at least onecable holder according to the invention and a method for assembling sucha domestic appliance.

DETAILED DESCRIPTION OF EXEMPLARY EMBODIMENTS OF THE PRESENT INVENTION

FIG. 1 shows a not yet completely assembled dishwasher having anappliance door 1 which opens or closes a front loading opening of adishwasher cavity 2 of the dishwasher. The door is bottom-hinged to thedishwasher so as to pivot about a horizontal axis in a known manner. Inthe completely assembled state, the appliance door 1 has in the usualmanner an inner metal plate 5 and an outer door element such as a fasciapanel or decor panel mounted thereto. In FIG. 1, the outer door elementhas been omitted for reasons of clarity so that the inner metal plate 5is revealed.

As can be seen from FIG. 1, a dispenser 7 for detergent dosing isincorporated in the appliance door 1. For mounting the dispenser 7, theinner metal plate 5 has an approximately central assembly opening 9 asshown in FIG. 2, from the edges of which mounting flanges 11 project onthe side facing away from the dishwasher cavity 2. The dispenser 7 asshown in FIG. 1 is pushed into the assembly opening 9 in a assemblydirection I until the snap-lock projections 15 provided on the edgefaces 12, 13 of the dispenser 7 engage behind the mounting flanges 11,as shown in FIG. 2.

For detergent dosing during a washing cycle, the dispenser 7 iscontrolled by an electronic control device likewise incorporated in theappliance door 1. The control device is also in signaling connectionwith an electronic low rinse aid indicator incorporated in the dispenser7. For problem-free, precisely defined cable routing between the controldevice and the dispenser 7, the power supply cables 17 are held in acable guiding element 19 which is shown in its installation position inFIG. 1. The cable guiding element 19 has, as shown in FIG. 1, two guidesections 21, 23 set at an angle α₁ of 90° to one another. These enclosevertical and horizontal edge faces 12, 13 of the dispenser 7 that arelikewise at right angles to one another. By means of the cable holder19, the cables are guided along the two edge faces 12, 13 as far as thelevel of the respective connection sockets (not shown) of the dispenser7.

The cable holder 19 is here a one-piece plastic injection molded partmade of uniform material. The two strip-shaped guide sections 21, 23 arepivoted together via a living hinge 25 and approximately half-enclosethe dispenser 7, the vertically installed guide section 23 in FIG. 1extending down beyond the lower housing edge of the dispenser 7. Thecables 17 are therefore looped around the lower end 26 of the guidesection 23 and return in the opposite direction to the correspondingconnection socket of the dispenser 7. The thereby created cable loopsenable any drops of liquid running along the cables 17 to drip off.

The, in the installation position, horizontally lying guide section 21of the cable holder 19 grips around the opposite housing edge 28 withits angled free ends 27. At the free end 27 of the horizontal guidesection 21 there is provided, as shown in FIG. 2, an elasticallyresilient clip which, in the installation position, presses against avertical edge face of the dispenser.

For lateral shielding of the cables 17, the two guide sections 21, 23 ofthe cable holder 19 have front delimiting walls 29. On each of the guidesections 21, 23, fastening clips 31 are additionally provided which fixthe cables 17 to the floor 32 of the guide sections 21, 23 of the cableholder 19.

The horizontal guide section 21 of the cable holder 19 also has, asshown in FIG. 2, elastically resilient snap-lock hooks 33. These arehorizontally aligned contrary to the assembly direction I and formedbelow the floor 32 of the guide section 21 on the front delimiting wall29.

For installing the cable holder 19 on the dispenser 7, the cableholder's horizontal guide section 21 is first pushed onto the upper edgeface 13 of the dispenser 7 in the horizontal assembly direction II asshown in FIG. 2, the horizontally aligned snap-lock hooks 33 beingguided by corresponding snap-lock openings 35 in the dispenser 7 untilthe snap-lock hooks 33 engage behind the corresponding snap-lockopenings 35. When the horizontal guide section 21 has been snap-lockedwith the dispenser 7, the guide section 23 is pivoted counter-clockwiseabout the living hinge 25 into its vertical installation position in theassembly direction III. In the installation position, a snap-lock pin 37provided on the vertical guide section 23 is snap-fit into acorresponding snap-lock receptacle 38 on the side of the dispenser 7.

For ease of handling of the appliance door 1 mounted to the dishwasheras shown in FIG. 1, a gripping bar 39 is formed on the floor 32 of theguide section 21. The gripping bar 39 extends approximately centrallyalong the guide section 21 on the side opposite the front delimitingwall 29. To pivotally actuate the inner metal plate 5 already hinged tothe housing of the dishwasher, the gripping bar 39 is grasped frombehind by the assembler and the actuating force F indicated in FIG. 1 isapplied. The upper snap-lock connection provided between the snap-lockhooks 33 and the snap-lock openings 35 of the dispenser 7 must bedimensioned accordingly in order to keep the cable holder 19 stable onthe dispenser 7 when the actuating force F is applied. To reinforce theupper snap-lock connection, additional snap-lock projections 41 can beprovided on the floor 32 of the guide section 21, as indicated in FIG.2. When the cable holder 19 is pushed onto the dispenser 7 in theassembly direction II, the snap-in projections 41 can provide additionallocking in conjunction with corresponding snap-lock openings 43 in themounting flange 11 of the inner metal plate 5. In this case the cableholder 19 is form-fit not only to the dispenser 7, but also to the innermetal plate 5.

As already mentioned, the cable holder 19 is made by plastic injectionmolding. The cable holder 19 is produced in an injection molding chamberwith folded-apart guide sections 21, 23 aligned lengthwise to oneanother, as shown in FIG. 3. The angle α₂ between the two guide sections21, 23 is 180° in the manufacturing position shown. Because of thefolded-out position of the two guide sections 21, 23, simple injectionmolding dies can be used, without additional slider components beingrequired.

Pre-assembly of the power supply cables 17 on the cable guiding element19 as shown in FIG. 4 also takes place in the lengthwise alignedmanufacturing position of the guide sections 21, 23 as shown in FIG. 3.For this purpose the cables 17 are clamped between the fastening clips31 and the floor 32 of the guide sections 21, 23. Pre-assembly takesplace in a common assembly plane, without the cables 17 having to beassembled round edges between mutually angled guide sections 21, 23 in acomplex assembly procedure. The pre-assembly position of the cableholder 19 as shown in FIG. 4 is therefore identical to its manufacturingposition shown in FIG. 3.

When pre-assembly is complete, the cable holder 19 with the cables 17fitted can be moved via the living hinge 25 to a packaging position, asshown in FIG. 5. In the packaging position shown, the two guide sections21, 23 are completely folded together. The cable holder 19 thereforeassumes an extremely compact, closed geometry in which the angle α₃between the two guide sections 21, 23 is reduced to zero. Cable holders19 folded together in this way can be packed or stored in a space-savingmanner.

To make the packaging position secure, the snap-lock pin 37 of the guidesection 23 that is vertical in the installation position engages in acorresponding snap-lock receptacle 45 provided in the floor 32 of theguide section 21 that is horizontal in the installation position. Thesnap-lock pin 37 therefore serves the dual function of laterally lockingwith the dispenser 7 in the installation position and locking with theguide section 21 in the packaging position.
